error: Uncaught (in promise) RuntimeError: memory access out of bounds

Trying to do a pretty simple HTML parse, and get WASM error:

deno run --allow-all scrape.ts
error: Uncaught (in promise) RuntimeError: memory access out of bounds

Offending line is just this:

const doc = new DOMParser().parseFromString(page.content(), "text/html"); // page from puppeteer

Is there anything special I should be doing differently or is this a bug?

Can you share the HTML that caused that error

I got the same issue

import { DOMParser } from "jsr:@b-fuze/deno-dom";

let text = response.text();
const response = await fetch("https://golem.de")
const doc = new DOMParser().parseFromString(text, "text/html")

@Robert-Ernst your code looks a bit incorrect so I fixed it and couldn't reproduce, it works for me:

import { DOMParser } from "jsr:@b-fuze/deno-dom";

const response = await fetch("https://golem.de")
const text = await response.text();
const doc = new DOMParser().parseFromString(text, "text/html")!;
console.log(doc.querySelectorAll("*").length);
console.log(doc.documentElement?.outerHTML);

what platform are you using and which version of Deno?
